BEGENERATZEVE FURNACE.

Application filed October 6,

To all whom it may concern: 7 Be it known that I, EMIL KIRGHBERG, engineer, a citizenot' the Gcrman'Empire, residing at Knappenbcrgerstrasse No. 112, Dortmund, in the Province of \Vestphalia and Kingdom of Prussia, Germany, have invented new and useful Improvements in Regcnerative Furnaces, of which the following is a specification.

The invention relates to a regenerating furnace below the hearth of which are placed, as usual, two gasand two air-chambers.

The special features of this invention are more particularly the arrangement of the gas and air-cl'ian'ibers, that of the dustchambers an! that of the funnels leading to the hearth, specially for the purpose of preventing the slag' from encinnbering the channels and of allowing the dust-chambers to be cleaned while the furnace is in work ing order, also with a view to maintain the furnace in perfect condition during a longer period.

In the accompanying drawing. 1n winch similar figures refer to similar parts throughout the several views, Figure 1 shows the furnace in longitudinal section, this section being taken on the left hand through the airgenerators and on the right hand through the gas-generators. Fig. 2 shows across-section. Fig. 3 shows two different plan views of which that shown on the left hand demonstrates more partieu--= larly the arrangement of the airand channels. placed between hearth and generators and the arrangement of the masonry, owing to which the chan11els.are accessible from the outside, whereas the ri 'ht handhorizontal section is illustrative of the con-- nection of the air-generators with the hearth.- The ground plan in Fig/ i shows on the other hand more particularly the position of the rcgencrators and of the gasand air-supply or cduction channeis respectively.

'At either side of the hearth a and an air-chamber 1, S and 2., t are arranged as usually. The air-chamber is mounted on both sides behind the gaschaml'wr, and the distributing casings for air and gas 5 and 6' are likewise placed behind one another in front ofthe furnaceand thev are connected to the gas and air-cluiabers by means of the cha'lmels 7 and 8. The channels 8 are made to pass between the gas chambers, by which i slag,

means these grow shorter in relation to the air-chambers,corresponding to the width'of the channels; likewise at the oppositethe exteriorsides the gaschambers are shorter than the airthzimbers. Owing to this and to the arrangement of the gasand air-channels behind each other-marked Stand 10- it has been rendered possible that these gasand air-channels, discharging at the sides of the hearth, can be conducted upwardly in a vertical direction Whereas heretofore they had to be'conveyed obliquely to the regenerators adapted in the center of the furnace. The dust-chambers 9, into which the gas channels discharge, are placed behind, relative to the dust-chambers 10 which at their top-end are connected to the air-channels, in

.order that there may be room enough for placing both chambers coadjacently. The dust-chambers 9 with the gas-channels as well as the chambers 10 are, as shown in Fig. 2, provided with slopingly asceariing soles 11 and the gas-chambers 9 are partly overhanging the air-chambers. This arrangement has allowed of laying the Vertical gas-channels as far as possible between the air-channels .or to distribute same regularly in such away, respectively, that the gasand air-channels, discharging into the hearth, arearranged in alternate succession. in orderto get, however, in spite of such distribution, freeaccess notjonly to the aircha niels, occupying their position pretty close to the outside, but also to the gas-channels, recesses 12 are arranged in the masonry of the front-walls where there are the channels 9, as shown in Fig. 1 on the right side and in Fig. 3 on the left side, allowing of their being opened from the exterior after having removed the bricks set loosely. T he gas distributed correspondingly and the air enter lhc generator-chambers, traverse same, pass then along through the channels placed rearwardly in the upper corner into the toppart of the dust-chambers and are nowtalten to the hearth by means of the vertical funnels i) and 10 and. the sloningly extending channels t)" and 10. The slags can no where deposit nor stick close, as it occurred formerly, all funnels 9 and 10 ascending vertically; they rather get without further trouble into the dust-chambers. Owing to their being arranged beyond the gasand air-chambers they can be readilycleaned during the operation, whereas, with other furnace the deposited on the slopings, can only be as i removed under difficulties after having en-. air channel, and a second dust chamber ar tirely stopped the furnace. ranged forward of the first dust chamber 1 chum: and commumentlng with the gaschannet.
